That board in the middle is the Tcon board. Make sure the fuse on the TCon is good and there is power going to it. You can verify the signals on the LVDS with an oscilloscope, whilst turning on and off the menu all the time and probing the LVDS pins.
Also we need voltage measurements of the PSU (ribbon cable that goes to the main board) with the TV on and off, to see what is really happening.Comment

There are 3-pin Voltage regulators such as IC5, ICR4 which has Voltage test points next to them telling you what the DCV should be, there are also other DCV test points on the boards as well, such as VCOMS1, 2, VGMAxx, VDD3.3, etc. so look at the board really well.

Hey Guys,
So a few months ago my Sony XBR 49x900e TV screen stopped displaying the picture but the backlight comes on and I still get sound when I use the remote and navigate to certain apps. I haven't checked anything with the meter yet but started with ordering some replacement boards. I've tried replacing the BMKS board (used from ebay) and also completed the firmware upgrade based on Nicks TV repairs youtube video. I've also replaced the TCON (twice) and PIB.

Hi Guys,
